Connection Setup

Step 1: Refer to drawing above on how to connect the light with the controller.

Step 2: For external triggering, connect the external trigger source with the trigger port.

Step 3: Connect the controller with an 100 - 240 V AC power source and switch the controller on. 

            The digital display is lit. If the intensity of the light shall be controlled via PC, you need to 

            connect the PC with an RS232 cable or Ethernet cable before the controller is switched on. 

            Use the provided software or your own application to communicate with the controller. 

            You can adjust the settings via the PC or manually.

Trigger Port and Setup

The trigger mode of this type controller is level trigger, so the trigger mode can be achieved by high voltage trigger,

low voltage trigger, rising edge trigger and falling edge trigger, and the connection COM port is the same in the controller.

The high power trigger (input voltage range is 5V to 24V) and low power trigger (input voltage range is 0V-2V) is separated

by the dual opto-couple inside. For the rising edge trigger and falling edge trigger, normally the delivered item is rising edge trigger,

but it can be adjusted to falling edge trigger by the trigger switch key on the panel.
